Sampling TCP Data-Path Quality with TCP Data Probes

In this paper, we present preliminary results of measuring TCP data-path quality using a new measurement tool called OneProbe. Unlike the existing tools, OneProbe uses legiti- mate TCP data probes to profile TCP data-path quality by sampling round-trip delay, one-way loss rate, and one-way reordering rate at the same time. This paper presents a set of recent measurement studies on a set of web servers hosting the Beijing Olympic Games in China and Hong Kong.
